These fluids dissolve silica and other minerals and deposit them in cavities or voids in the rocks. Over time, the deposited silica accumulates and recrystallizes, forming layers of chalcedony. The plume-like inclusions are formed when trace minerals in the hydrothermal fluids mix with the silica during the recrystallization process. \u003c\/span\u003e\u003cspan\u003eThe coloration depends on the specific trace minerals involved.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eEnjoy!\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e:\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cmeta charset=\"UTF-8\"\u003e\n\u003cdiv\u003eLarge 1\/2” \/ 13mm Round, Double Flare Plugs\u003c\/div\u003e\n\u003cdiv\u003e12mm Total Thickness. 10mm Wearing Surface.\u003c\/div\u003e\n\u003cdiv\u003e15mm Front flare. 14.5mm Rear flare.\u003c\/div\u003e\n\u003cdiv\u003eFlat faces front and back.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003ePlease allow for +\/- 0.25mm discrepancy as these are all hand made pieces of art.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e","brand":"Grit Lapidary","offers":[{"title":"Default Title","offer_id":51314625577238,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/8673\/3590\/files\/Photoroom_20260508_041301.jpg?v=1778786649","url":"https:\/\/grit-lapidary.myshopify.com\/products\/large-1-2-13mm-dendritic-plume-agate-1","provider":"Grit Lapidary","version":"1.0","type":"link"}
